Abstract
An electric motorincludes a first structureincluding a magnetic pole row formed by a predetermined plurality of magnetic polesarranged in a predetermined direction, a second structureincluding an armature row disposed in a manner opposed to the magnetic pole row, for generating moving magnetic fields moving in the predetermined direction between the armature row and the magnetic pole row, and a third structureincluding a soft magnetic material element row. The third structure disposed such that the soft magnetic material element row is positioned between the magnetic pole row and the armature row. A ratio between the number of the armature magnetic poles, the number of the magnetic poles, and the number of the soft magnetic material elementsis set to 1:m:(1+m)/2 (m≠1.0).
